Testing Methods

Non-destructive and destructive testing methods in materials testing

Ultrasonic Testing

Ultrasonic testing (UT) uses high-frequency sound waves to detect internal flaws, measure thickness, and characterize materials.

EN ISO 16810, DIN EN 1714, ASTM E164

NDT

Radiographic Testing

Radiographic testing (RT) uses X-rays or gamma rays to produce images of the internal structure of components to detect defects.

Magnetic Particle Testing

Magnetic particle testing (MT) detects surface and near-surface discontinuities in ferromagnetic materials using magnetic fields a…

NDT

Penetrant Testing

Penetrant testing (PT) uses capillary action to detect surface-breaking defects in non-porous materials.

NDT

Visual Testing

Visual testing (VT) is the most basic NDT method, using direct or remote visual examination to detect surface defects.

What is Materials Testing?

Materials testing covers all methods for determining the properties of materials. It is divided into non-destructive testing (NDT) and destructive testing.
